a. Download student course data from the following URL into a dataframe as follows: url = http://www.akyokus.com/COE-101-Grades.xlsx print students data. b. Suppose that midterm I has %25 weight, midterm II has %25 weight, and final has %50 weight. Calculate the avegrage of each. c. Convert each of NaN values to zero. d. Suppose that the letter grades is evaluated as follows: If NumberArg >= 94 Then GRADE = "A+" Else If NumberArg >= 87 Then GRADE = "A" Else If NumberArg >= 79 Then GRADE = "B+"

Print students data along with grades. e. Assume that the passing grade is C. Find the students who failed the course. f. Assume that the passing grade is C. Find the students who passed the course g. Prepare a pivot table that shows the count of students that took A, A, B+, B,..,F. f. Prepare a histogram graph that shows the count of students that took A, A, B+, B,..,F. g. Prepare a pie graph that shows the count of students that took A, A, B+, B,..,F. h. Find the correlation between MIDI and MIDII, and between MID II and FINAL. Make an interpretation about the correlations that you found. i. Find the average of MIDI and MIDII grades. Find the students whose final grades increased more %10 than the average of MIDI and MIDII grades. Make a listing of these students.
